About HDD Firmware:

Updating the HDD’s (Hard Disk Drive) firmware version can fix various problems that might occur, enhance some of the features available or add support for new ones, and improve the unit’s overall performance.

However, as this task can be very risky, applying a different firmware is recommended only when the newer version specifically resolves an issue that bothers you, or brings about changes that you can make full use of.

In addition to that, make sure you perform this task only in a steady power environment (such as the one ensured by a UPS unit).

As for the update process, due to the wide variety of HDDs and various methods provided by each manufacturer for installing a new firmware, it would be best if you carefully read and understand the installation steps.

That being said, if you consider updating the HDD to this firmware version, click the download button, and make sure you read the installation guide before initiating the upgrade. Moreover, constantly check with our website to stay up to date with the latest releases.
